GnuPG uses a number of block ciphers in a variant of CFB mode.
See RFC 4880, section 13.9 for more details on the mode of operation.
btw, can someone explain to me what the design rationale for that
"variant" is? I did not find an explanation in the RFC as to *why* the
design choices were made in that particular way.
